The round

Mining a round

Mine any tiles you like while the round is open. You choose one amount per tile, so mining five tiles at 0.01 costs 0.05. One entry per round per wallet: once your tiles are in, they stay in until the draw. Pick more than one round and the same tiles are mined in the rounds that follow, starting from the next round, paid up front together with a small fee for the executor that places each one. Each counts as your entry for that round, and you can stop at any time: the rounds not yet mined are refunded.

When the 60 seconds are up the round closes and Flap's trigger service settles it on chain. Usually within seconds the drawn tile lights up, and the next round is already open.

The draw is uniform

Every tile has exactly a 1 in 25 chance, however much is mined on it. Mining more on a tile changes your share if it is drawn, never whether it is drawn.

Everyone on the drawn tile shares the round's payout in proportion to what they put on that tile. If nobody mined the drawn tile there is no payout: the whole round goes to buybacks and the goldpot, and no MING leaves the reserve.

The numbers

Covering every tile

Mine all 25 tiles and you are always on the drawn one, so you always share its payout. That is not free: the fees come off the round first, and the rest is split with everyone else on that tile, plus the MING. The interface labels those rounds "covered all" rather than "paid".
